Problem with weapon lists...

Code:
obj
    Axe
        desc = "A sturdy axe."

    Sword
        desc = "A sharp sword."

    Hammer
        desc = "A large hammer."




// Under mob, under the login proc

        usr.Weapons.Add("Axe","Sword","Hammer")





// and this is the verb under mob I'm having trouble with...

    checkweapons()
        var obj/W = input("Your weapons") in Weapons
        world << W.desc


Problem description:


Everything else works fine except when i hit the checkweapons and select a weapon choice, it says:

runtime error: Cannot read "Axe".desc


I assume it has to do with the part that it is text, and not just an object? I'm not sure, please help, I'm fairly new.

usr.Weapons.Add("Axe","Sword","Hammer")


I would've used src instead of usr in this case, but basically what you are doing here is adding text strings to the list instead of objects. You need to create a new instance of the object classes and add those to the list instead. Something like this:

var/obj/Axe/axeInstance = new()
var/obj/Sword/swordInstance = new()
var/obj/Hammer/hammerInstance = new()
src.Weapons.Add(axeInstance,swordInstance,hammerInstance)

To be honest I always find it funny how people believe knowing whether an axe is sturdy or not is really helping. Sometimes it's good to know details but most items should be interpretable from their name alone.

I agree. And really, unless you plan on throwing items in that are destroyable through use like and old axe might only be usable 3 times were as a new axe maybe 10 or a rusted axe maybe 5 times. If all the axes are the same and have the same usability, you really don't need to describe them.

But his question had nothing to do with semantics, personal preferences or design philosophy--it was a question as to why his program wasn't working.

But Cody was right. The problem is in using a text string as opposed to an atom. He helpfully provided useful information, so I won't echo him further.

Well you know, i was planning on generating everything's details from double sided axes to rusty old crappy ones, thanks for helping guys, it was mostly a test, haha.

I'm not sure if that's the best way. That way requires a lot of lines of code.

var/list/weapons=list(/obj/Axe,/obj/Sword,/obj/Hammer)

mob/Login()
    ..()
    for(var/T in weapons)
        src.Weapons.Add(new/T())


This way, you can add more types to the weapons list without having to add many more lines of code and declare new variables.

If you wish to be that way, simplified further...
mob/Login()
 ..()
 src.Weapons.Add(new/obj/Axe(),new/obj/Sword(),new/obj/Hammer())


Not too much difference in any of the methods provided.

mob/Login()
    ..()
    for(var/t in typesof(/obj/weapon) - /obj/weapon)
        Weapons.Add(new t)


No need to specify a weapons list, as long as they all come off the same root in the tree.

Flavour text. The sentences "you see a brute" and "you see an intimidating, well-built brute" are equivalent (the latter can be inferred from the former), but give off a different feel.
